Compare and contrast two cities Essays

Compare and contrast two cities Essays Compare and contrast two cities Essay Compare and contrast two cities Essay The greatest celebration in Kazakhstan is called Nauriz Eve. There is a legend in Central Asia that every year during the night between the 21st and 22nd of March (the spring equinox), the wise elder Kadyr-Ata walks across the Earth. Kadyr-Ata brings people happiness and wealth, and he also possesses special magical powers. At three oclock in the morning, Kadyr-Ata opens the door to the sky and lets Spring come to the land. At this time, he breathes life into the earth; in essence he renews he earth from its dreadful winter state, and brings life back to spring. Nauryz symbolized the birth of a new year, cycle of life and Kazakhs came together to celebrate as a community. In Kazakhstan Nauryz is truly a social event. Now People in my country gather together at their main city, squares, where holiday organizers erect yurts, stages, and trading tents where crafts and goods are sold. Food is cooked on open fires in huge pots, and people dress festively. The roots of the holiday are ncient, and it is believed that the roots of Nauryz began at least 2000 years ago, most likely in Persia. Nauryz- is celebrated mostly in Muslim countries, but it is not a religious holiday. Nauryz is a traditional celebration of the spring equinox celebrated today by many nations throughout Asia and Europe, including Russia, Ukraine, Japan, and China There is a traditional belief that people will spend their new year in a manner similar to the way theyVe celebrated Nauryz. So, in the spirit of the season and a desire to have a comfortable year, people work hard to clean their homes, they wear their best clothing, and they cook a lot of delicious food. Indeed, the Nauryz table has important symbolism: the more food you have on your table, the better and more sufficient your life may be in the coming year. Nauryz is celebrated in every school in Kazakhstan, and has been since the downfall of the former Soviet Union. I remember the very first Nauryz in my school. We put insulation on the ground of our court (it was still pretty cool outside) and covered it with Kazakh rugs. Each grade decorated its own corner and every grade tried to organize a better table than all the others. It was almost a competition n whose table was richer! One of the grades even erected a real yurt right in the court of our school. In conclusion, these three countries celebrate their holidays in unusual and traditional ways, and this makes their culture unforgettable for all generations.

Learn More About Georg Ohm and Ohms Law

Learn More About Georg Ohm and Ohm's Law Georg Simon Ohm was born in 1787 in Erlangen, Germany. Ohm came from a Protestant family. His father, Johann Wolfgang Ohm, was a locksmith and his mother, Maria Elizabeth Beck, was the daughter of a tailor. Had Ohms brothers and sisters all survived he would have been one of a large family but, as was common back then, several of the children died young. Only two of Georgs siblings survived, his brother  Martin  who went on to become a well-known mathematician, and his sister Elizabeth Barbara. Although his parents had not been formally educated, Ohms father was a remarkable man who had educated himself and was able to give his sons an excellent education through his own teachings. Education and Early Work In 1805, Ohm entered the University of Erlangen and received a doctorate  and immediately joined the staff as a mathematics lecturer. After three semesters, Ohm gave up his university post. He could not see how he could attain a better status at Erlangen as prospects there were poor while he essentially lived in poverty in the lecturing post. The Bavarian government offered him a post as a teacher of mathematics and physics at a poor quality school in Bamberg and he took up the post there in January 1813. Ohm  wrote an elementary geometry book while teaching mathematics at several schools. Ohm began experimental work in a school physics laboratory after he had learned of the discovery of electromagnetism in 1820. In two important papers in 1826, Ohm gave a mathematical description of conduction in circuits modeled on Fouriers study of heat conduction. These papers continue Ohms deduction of results from experimental evidence and, particularly in the second, he was able to propose laws which went a long way to explaining results of others working on galvanic electricity. Ohm's Law Using the results of his experiments, Ohm was able to define the fundamental relationship between voltage, current, and resistance. What is now known  as Ohms law appeared in his most famous work, a book published in 1827 that gave his complete theory of  electricity. The equation I V/R is known as Ohm’s Law. It states that the amount of steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The ohm (R), a unit of electrical resistance, is equal to that of a conductor in which a current (I) of one ampere is produced by a potential of one volt (V) across its terminals. These fundamental relationships represent the true beginning of electrical circuit analysis. Current flows in an electric circuit in accordance with several definite laws. The basic law of current flow is Ohms law. Ohms law states that the amount of current flowing in a circuit made up of only resistors is related to the voltage on the circuit and the total resistance of the circuit. The law is usually expressed by the formula V IR (described in the above paragraph), where I is the current in amperes, V is voltage (in volts), and R is the resistance in ohms. The ohm, a unit of electrical resistance, is equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.
